Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493466, here are decompositions:

347 + 2147493119 = 2147493466
389 + 2147493077 = 2147493466
449 + 2147493017 = 2147493466
827 + 2147492639 = 2147493466
857 + 2147492609 = 2147493466
977 + 2147492489 = 2147493466
1019 + 2147492447 = 2147493466
1283 + 2147492183 = 2147493466

Showing the first eight; more decompositions exist.
